It used to be that TV was so mediocre that it wasn't really worth discussing. Then TV got a lot better, but we didn't have much of a place to discuss it. Then Alan Sepinwall, who was the TV critic for the Star-Ledger hung out his shingle online, recapping episodes and spurring plenty of discussions. Today you can hardly browse the internet without someone trying to figure out what happened on Homeland last week. (We haven't started the series yet. So don't spoil it!) Sepinwall's current digs, at Hitfix's What's Alan Watching, are some of the internet's best places to read and chat. But right now he's chatting with us, here, on the occasion of the release of his new book, The Revolution Was Televised: The Cops, Crooks, Slingers and Slayers Who Changed TV Drama Forever.
